This is an interesting....
...and one that I probably should have included in the "Cutting Edge" item. Yes, I think using a lanyard on your knife is a very good idea. Mine are (I use 2 different knives) long enough to allow me to use the knife with my arm fully extended. As you may have guessed, I have a number of favorite knives, and each seems to have a particular lanyard. The one I like best is a piece of 3/16" 3-strand nylon with eye splices at either end. I do not recommend splicing the loop around the knive cringle/bale as you may want to detach it at some times. I use a plastic clip to attach the knife to the lanyard and then run the other end thru a belt loop and then thru eye splice in that end. Very nautical looking...My other knife has a 1/8" nylon braid that I've used a hangman noose knot on either end to secure the knife to it and for a loop to go through my belt loop. Sorry for the windy reply, but I love this subject....
